HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters IlPatent No. 410,196, dated September 3, 1889;

Application filed April 30,1887. Serial No. 236,611. (No niodel.)

To on whom, it may concern:

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex,

and State of Massachusetts, a citizen of the United States, have invented a new and use-j ful Improvement in Heel-Nailing Machines,

the last or work-support to compress the heelblank upon the outsole of the boot or shoe.

It further relates to a heel-attaching machine having a templet movable in relation to the heel-support, as above specified, in combination with the nail-driving devices.

It further relates to the templet movable in relation to the heel-support, as above specified.

moving it either directly or indirectly.

Fig. 5 is a plan view of the nail-carrier. Fig.

- 6 is a view in front elevation of a portion of the post supporting the templet-lever. Fig. 7 is a View in vertical central section of a machine having the features of my invention, showing the nail supplying and distributing device in elevation.

Referring to the drawings, A represents the frame of the machine.

a is the table, upon which slides the jack a, which supports or carries the last or worksupport a.

B is the templet. It is mounted at the front end of the lever or pivoted holdingplate I) in a manner to be removable therefrom. This lever or pivoted holding-plate is pivoted at b to a post or support b has the long arm b and is provided with movements for moving the templet toward and from the last or work-support by the cam 0 upon the shaft 0, the lever c, pivoted at 0 and connected by means of a cam-pin o with the cam,-

and by means of the link 0 with the links 0 c of the toggle 0 connected with the slide-rod or connection 0 which is guided in a suitable guideway in the bracket 0 The upper end of this slide rod or block is connected by means of an adjustable connection 0 with the end of the lever or.plate b. The adjustable connection shown ;comprises the two parts 0 0 The part c is connected by a link 0 with the end of the lever 6 The part 0 is the upper part of the slide block or rod a The continuous ends of the parts 0 0 have screw-threads, which are opposed to each other, and each receives the adjusting nut or connection c The cam is timed or constructed so as to provide the templet with any desired movement or movements in relation tothe last or work-sup- It also relates to a templet movable as above specified, anda cam for operating or port.

Generally the movement will be as follows:

work-support, with the boot or shoe mounted thereon and with the heel-blank in position, is placed beneath the templet. The templet is immediately swung downward to compress the heel-blank upon the outsole of the boot or shoe, and the heel-blank is held thus compressed during the forming of the awl-holes by the awls and the feeding of the attachingnails and the driving of the same by the drivers. If the heel is to be blind-nailed, then the cam is constructed to move the templet away from the attaching heel blank sufficiently to permit the top-lift plate, with the top lift, to be inserted between the attached heel-blank and it, and it is then moved again to compress the top-lift plate and top lift so that the top lift is spanked upon the ends of the heel-attachin g nails. If the attach ed heel is breasted in the heel-attaching machine, the templet remains in place during the operation of the breasting device, and it is then lifted The link 0 of the toggle is 3 Upon the starting of the machine the last or It further relates to various features of:

to release the work. If it is not breasted, then employed, and it maybe operated by hand or automatically. I prefer that the nails be fed automatically, and have represented a carrier not unlike that represented in my patent, No. 329,951, excepting that it is used for the main or principal attaching-nails instead of for the auxiliary nails, as herein specified. D is the carrier. It is supported by the arm (Z of the revolving head D. This revolving head is carried by the reciprocating head D and is adapted to be automatically rotated by m echanism substantially as described in the Henderson and Raymond patent, No. 3126M, or in my pending application, or in the pending application of O. 0. Small.

The revolving head has the arm (1, which supports a block carrying a gang or group of awls (1 the arm (I, above referred to, which also supports a block carrying a gang or group of drivers (i and an arm (1*, which may carry a breasting-knife.

The arm (1 has a central hole (1 which receives a post d, attached to the nail-carrier. This post bears on a coiled spring (Z which tends to move it outward or away from the arm (Z. The drivers are carried by a block attached to the arm (1, and their ends enter the holes 6 of the carrier when the carrier is moved outward to its greatest extent from the arm (Z.

(See Fig. 1.) The carrier D receives its nails from asuitable nail making and distributingmachine E, (see Fig.7,) which is mounted upon a support 6, so as to deliver nails to the carrier D when the head has been rotated sufficiently to bring the carrier beneath the nail making and distributing machine. The said nail making and distributing machine E may be of any preferred construction and of the form of nail- -feed1ng mechanism described in my various carrierD rotates into position the edge of the plate al comes in contact with it and is moved sufficiently to bring its holes in register with the holes of the carrier. Upon the rotation of the head D to bring the carrier into position :to'deliver nails into the templet the spring d automatically moves the slide-plate (Z to close the holes, and the plate remains in this position until the carrier is brought into position over the templet and is beingmoved downward in relation thereto, when the edge of the plate is brought into contact with the projection 61 on the templet-support, which causes the slideplate to be moved sufficiently to bring its holes in register with the holes of the templet and the holes of the nail-carrier before the slide-plate is brought in contact .with the uppersurface of the templet, thereby permitting the nails to leave the carrier and enter the holes of the templet.

The mechanism for rotating the head D is so timed that it turns the head a quarter of a revolution during each reciprocation thereof and stops with the nail-carrier D in position to receive nails from the nail-feeding device E. Consequently, upon the starting of the machine the awls are in a position to be moved into place to register with the holes of the templet during the upper part of the downward movement of the cross-head D This movesthe drivers and nail-carrier D into the position which the awls occupied before such movement. The next reciprocation of the head D brings the nail-carrier D and. drivers over the templet during the upper part of the downward movement of the head, and as the'head is moved downward the nail-carrier covering-plate d is moved and the holes of the carrier uncovered, so

- that the nails drop therefrom into the holes of the templet and the nail-carrier comes to rest upon the upper surface of the templet. The head D however, continues to descend, and the drivers then move in the carrier through it and into the templet, driving the nails therefrom into the heel-blank and soles of the boot or shoe. Upon the upward movement of the cross-head the drivers are returned to their original position in relation to the carrier and the head rotated another quarter of a revolution to bring a breastingknife adapted to be attached to one member or arm of said head into position, and upon the next quarter-revolution of the head the carrier is moved into position beneath the nail-supplying mechanism E, the slide-plate al moved to open its holes, and the nail-supplying mechanism set in operation to automatically feed nails to the holes (1 of the carrier.

I would say that this device for carrying and driving the attaching-nails may be used without a templet for certain classes of' work, in which event the nails would be delivered directly to the work and driven directly therein without the employment of an y additional templet than that provided by the holes of the carrier D. I would further say that I do not confine myself to the specific mechanism herein described for operating the templet-lever b. In lieu thereof,the lever or pivoted plate or support I) may be connected directly with an actuating-cam, as represented inFig. 7.

By making the templet B movable in the manner specified a ver; powerful compressive force is obtained and one that can be utilized before the awls are caused to puncture the heel-blank.

Instead of forming the templet B as a sepa rate block and detachably securing it to the end of the lever or pivoted plate or support I), it may be formed in the end of the lever plate or support by drilling the necessary holes through the same.

plet formed on or supported bya pivoted le- I would here say that the heel-blanks and top lifts may be automatically fed intop0sition between the templet and last or Worksupport, as described in my application filed April 16, 1887, orinthe application of C. 0. Small, filed April 19, 1887.

The templet is constructed of such proportion and is so timed in its movements as not to interfere in any manner with the proper operation of a breasting-knife mounted as hereinbefore referred to.
